FordService Report post Posted August 18, 2015 ...Our Ford Rep is asking her sources, maybe we'll get their answer soon... Hi guys, I just heard back from my sources. As that information is proprietary, I'm unable to provide it. It's recommended that you use the same as what was originally equipped, unless a TSB/FSA updated it, which your dealer would be able to determine.
